T0 (LZZ whom it may concern:

Be it known that I, WILLIAM J. CLARK, a

resident of Elmhurst, county of Queens, State of New York, haveinvented certain new and useful Improvements in Top Burners for Gas- Ranges, of which the following is a full, clear, and concise specification.

My invention relates to top burners for gasranges, and more, particularly has relation to an improved form of, construction and novel disposition of parts whereby the burners are readily and freely removable from the range to permit of the latter being easily cleansed of the dirt and drippings from'cooking, &c.;

. and the object of my invention is the provision of simple means whereby the top burners after removal may be easily replaced in their original proper positions by persons unfamiliar with the mechanical arts or the construction or principleof gas-burning ranges. My lnventlon also lnvolves other novel features of advantage hereinbelow fully described, and more particularly pointed out in the claims.

Reference is made to the accompanying one sheet of drawings, in which Figure 1 is a top plan view of the top burnverse sectional view of Fig. 1 on the line a a.

, range in-any convenient manner.

Reference character 1 indicates the top plate ofa gas-range, which may be of any design and is mounted on the side walls 2 of the The gassupply pipe 3 is ledfrom a point in the rear to and across the front of the range, where it is supported by suitable brackets, as indicated. A series of stop-cocks 4, equal in num her to the number of burners, is tapped into the supply-pipe, and these cocks have reduced ends forming nozzles 5, adapted to emit a comparatively fine stream or jet of gas into the burners 6. The latter are of the usual wellknown style, being hollow bodies havingtop perforations and hollow shanks or tubes. connecting their interiors with 'the gas-supply nozzles 5. The gas-receiving ends of the tu- Bunsen burners. I

It is essential in burners of this class that the gas and air be properly mixed before pass ing to the top perforations, and it is found from experience that it is impossible for thorough mixing to take place unless the receiving ends of the burners are in their proper predetermined position with respect to the jet of gas. The axis of the receiving end of the tubular shank must preferably be in substantial alinement with the axis of the jet.

A very slight deviation from this position is apt to cause imperfect mixing of the gas and air by the impingement of the gas against the walls of the tube and gives rise to the striking back of the flame and other objectionable actions which reduce the efficiency of the range. It hastherefore been the custom heretofore to prevent displacement of the burners by securing them permanently to the range by screws or bolts, as in this way only has continued satisfactory-operation been assured; but permanent attachment is objectionable on account of-the difliculty and inconvenience in cleaning the range. By the present improvement the burner is allowed to be removable'and at the same time is readily replaceable into its correct position and when replaced is not liable to be disarranged. This desirable result is obtained by forming the burners with V -shaped crotches, as shown'in Figs. 2 and 3, adapted to engage and rest upon a transverse rib or rod 7, secured to the range.

The rods 7 are preferably mounted, as shown, in the side walls or framing of the range and are so adjusted with respect to the nozzles 5 that When the open .end of a burner-shank is slipped over the nozzle the V-shaped crotches on its other end will engage with a rod and slide down over it until fully seated thereon. In this position the rod will be as near as possible to the apices of the crotches, as shown in Fig. 8, and by reason of the previous permanent adjustment of the red the tubular shank of the burner will thus be caused to assume the proper vertical as well as the proper horizontal position with respect to the jet of gas. The crotehes on the burners may take the form of depending lugs, as shown in the drawings, or a V-shaped depression or notch may be formed inthe hollow burner-body. It is obvious that one rather long notch will take the place of the two lugs indicated in Fig. 2, provided it is sufficiently long to give the burner adjustment in a horizontal direction as it seats itself. The angle of the notch is of course sufficiently acute to enable it to seat fully on the red by its own weight.

With the construction just described it will be obvious that a burner may be removed by simply grasping it and drawing it off of the nozzle and that it may be replaced by slipping the open end over the nozzle again and dropping the other end upon the rod, whereupon the weight of the burner will cause it to ride downward on the rod, thereby bringing the gas-receiving end of the shank into proper alinement with the jet of gas.

Having described my invention, what I desire to claim and wish to secure by United States Letters Patent is 1. In a gas-range, a gas-inlet nozzle and a transverse support, a burner having an open end removably supported adjacent said nozzle, in combination with a V-shaped notch on said burner adapted to engage said transverse support, whereby the burner is :uitomatically seated in correct position with respect to said nozzle.

2. In a gas-range, a gas-inlet nozzle and a transverse support, a burner having a gas-receiving end and means for removabl y supporting the same adjacent said nozzle, in combination with a pair of crotches on said burner adapted to engage and be supported by said transverse support, whereby the burner will assume correct relative position with respect to said nozzle.

3. In a gas-range, a gas-inlet nozzle and a transverse support secured to the walls of the range, a burner having an open gas-receiving end removably supported by said nozzle, in combination with a V-shaped notch in the other end of said burner adapted to engage with said transverse support whereby the burner is caused to assume proper air-aml-gas mixing position with respect to said nozzle.

4. In a gas-range, a gas-inlet nozzle and a transverse rod secured to the walls of the range, a burner having an open gas-receiving end fitting and supported by said nozzle. in combination with a pair of depending lu having V-shaped notches adapted to engage said rod and thereby cause the burner to assume a proper position with respect to the nozzle.

In testimony whereof I have signed my name WM. J. CLARK.
